FIRE-PLACE FRAME.-

SPECIFICATION forming part of Letters Patent No. 265,834. dated October10, 1882.

Application filed June 521, 1882. (No model.)

To all whom it may concern:

Be it known that we, JOHN J, LEBEAU and CHAS. L. SHANNON,of Cincinnati,in the county ot'Hamilton andState of Ohio, have invented certain newand useful Improvements in Fire- Place Frames, of which the following isa specification.

Our invention is in the nature ofan improvement in the frames of gratefire-places, and

[O has for its object, first, the construction and arrangement of thejambs in such a manner that they maybeadjusted to slightlyvaryinglengths of tire-baskets; and, second, in providing a throat inthe top 'of the frame, which, in conjunction with a movable plate,enables the fireplace to be etfectuallyclosed against downdraft when thegrate is out of use, as in summer.

Our invention consists ofaback plate of castiron, which is furnished ateach end with vertical flanges disposed at right angles to the back, towhich flanges are attached, by means of screw-bolts, the sidejambs ofthe fire-place. Attached to the top forward edges of the two side jambs,by means of screw-bolts, is a crossplate, the bolt-holes in which areslotted to permit of moving the jambs inward or outward to receivedifferent lengths of fire-basket. The space between the back edge of thecross-plate and the upper edge of the back plate forms a 0 throat, overwhich is titted a tilting plate,which, when closed, rests upon the edgesof the throat, and when opened is supported by brackets on the backplate and by brackets cast upon its upper surface, which latter are sodisposed with 5 relation to the brackets on the back plate as to guidethe tilting plate and retain it in position on the frame, all of whichwill be fully described hereinafter.

In the accompanying drawings, Figure 1 is a sectional elevation of ourimproved frame, showing the tilting plate thrown back and the throatopen. Fig. 2 is a similar section, showing the tilting plate down andthe throat closed. Fig. 3 is a perspective front view of the frame,

The brackets a aare preferably cast with the back plate, A. The separation of the outersurfaces of the brackets d (Z is slightly. less than the separation ofthe inner surfaces of the brackets a a, whence the brackets d cl and a amutually serve as guides and stops to limit the motion of the plate Dand to retain it in position An eye, d, which may be cast with thetilting plate D, enables it to be drawn forward to close the throat whenthe fi replace The throat D connects the grate and the flue formed inthe chimney-breast, as clearly shown in Figs. 1 and 2. So long as thegrate or tireplace is in use the throat D is open, as shown in Fig. 1;but when it is out of use-as, for instance, in the summer season-thethroat is closed, as shown in Fig. 2, whereby all downdrafts fromcontrary gales are avoided. The necessity ot'elosing the connectionbetween the fire-place and the flue is generally recognized byhousekeepers, who, for the lack of a better means, are accustomed tostuff the throat of the fireplace with rolls ot' paper or rags to prevent the downdralts and avoid the consequent injury and inconvenience ofshowers of soot and dust.

The advantage of the adjustable side jambs to compensate for slightvariations in thelength of fire-baskets will be appreciated bygrate-setters, who frequently find tire-place frames furnished withbaskets so long as to refuse to enter the frame, or so short as to havea precarious support on the customary hooks cast upon the backs andsidejambs, as shown at l) and a Having described our invention, what 'weclaim is 1. In a lire-place for grates, the combination of thehorizontal top plate, 0, the side jambs, B B, having their upper endsadjustably connected with the ends of the top plate, and the verticalback plate, A, connected with the rear ends of the side jambs,substantially as described.

2. In a fire-place for grates, the combination of the top plate, 0,having slots 0 at its ends, the side jambs, B, having flanges I)adjustably connected with the top plate by boltsc passing through theslots in the latter, and the back plate, A, having flanges a. connectedwith the rear ends of the side jamb by means of bolts 1), substantiallyas described.

3. In a fire place frame for the reception of a fire basket or grate,the tilting plate D, provided with brackets 01 d, in combination withthe back plate, A, having brackets a a, substantially as and for thepurpose described.
